{"product_id":"3-0-stainless-steel-catted-downpipe","title":"3.0\" Stainless Steel Catted Downpipe","description":"The RV6 Performance High Temp Catted Downpipe is engineered to enhance the performance of the 2018+ Honda Accord 2.0T (K20C4) engine. Utilizing SolidWorks 3D modeling and Creaform 3D laser scanning, this downpipe ensures precise fitment with the turbo-flange and chassis. Its construction features 304 stainless steel with precision-cast transitions and a 3.0\" OD outlet designed to connect seamlessly with factory or aftermarket exhaust systems.\n\nThe core of this downpipe is a high-temperature, 300-cell metallic catalyst, developed in collaboration with the catalyst manufacturer to withstand sustained boost pressures that would typically melt standard catalytic converters. The construction is fully TIG welded with argon back-gassing, ensuring clean and pure welds both internally and externally. Factory heat shield mounting points are retained for ease of installation and heat management.\n\nInstallation of this performance downpipe requires a race tune, such as those from KTuner or Hondata. The product includes necessary hardware: 3 Chromoly exhaust studs, 3 locking nuts, and a graphite gasket with a blowout-resistant sealing ring. Optional ceramic coating is available for reduced under-hood heat transfer and an improved visual finish, though it adds an additional 7–14 business days to processing time.\n\nRV6 Performance offers a 24-month warranty on the castings and welding of this downpipe. However, there is no warranty on the catalytic converter core itself, as it is considered a consumable part susceptible to damage from improper tuning, misfires, or rich air-fuel ratios. Running this aftermarket downpipe on a stock tune may result in check engine lights and rich-fueling conditions.","brand":"RV6 Performance","offers":[{"title":"Default Title","offer_id":52663571120440,"sku":"RV6-ACC-DPC","price":799.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687659500.jpg?v=1784328125","url":"https:\/\/store.motormia.co\/products\/3-0-stainless-steel-catted-downpipe","provider":"MOTORMIA","version":"1.0","type":"link"}
